This invention relates to athletic shoesfor wear by football players, golfers, track athlctes, and for analogous purposes in which devices-in the nature of calks, cleats, spikes,

5 etc., are designed to prevent slipping on the ground.

The object of the inventionis to provide improved means for securing cleats or the like to such a shoe, firmly, so that they will not become loose accidentally, and yet detachably in such a way as to permit convenient removal and substitution of the other cleats.

In this specification, the term cleat is used in a generic way to typify and include any of the ground engaging projections which may be applied to shoes in accordance with this invention, such as cleats, cleats or calks for use on a football field in dry weather, the so-called mud cleats, used when the ground is soft and muddy, and spikes for track shoes adapted to various devices and conditions on running tracks, etc.

The invention is embodied in an athletic shoe attachment comprising a cleat having an externally threaded shank, and an anchoring member in the shoe bottom including an internally threaded bushing adapted to detachably engage the cleat shank, said cleat and anchoring member having means for preventing the tipping or rocking of the cleat .in any direction on the shoe bottom. and accidental unscrewing rotation of the cleat, means being provided for preventing rotation of the bushing while the cleat is being applied or removed.

' The principles and details of the various embodiments of this combination, and the related attributes of the invention are shown 40 in the drawings and described in the following specification.

In the drawings, Figure 1 is a perspective view showing a portion of the athletic shoe having attachments according to this invention.

The same reference characters indicate the figures.

'10 represents the bottom of a shoe which may be the outsole, or a tap sole, and is pro- The term cleat as previously stated, comprises calks, or projections of any character adapted to be detachably secured to the shoe in accordance with this invention. The cleat comprises essentially a body 11, a rigid base 12, and a protruding externally threaded shank 13, adapted to be engaged with an internally threaded bushing or socket in the shoe bottom. The base 12 in this embodiment of the invention, is recessed at the side which comes ing annular ridge 14, concentric with the shank 13 and of appreciable width, in order to provide a narrow enough contracted area to indent the tread face of the shoe bottom sufiiciently to hold the cleat firmly when screwed up tight, but not sharp enough to out the material of the bottom. For some purposes, as with football and 01f shoes, the cleat bodies 11 being of su stantial bulk preferably may be made of a moldable composition such as hard rubber, bakelite, etc. earing on a metal base 12; the base for that purpose being of metal and having a wing pro ection 15, or an equivalent device of other design, adapted to be embedded in the molded composition to anchor the body firmly. The

. ing or sleeve portion 16, forming a socket complemental to the shank 13, an anchoring head or flange 17, projecting to a substantial distance laterally from the socket on the inner end thereof, and means for securing the anchoring member against rotation when the calk is applied or removed. One type of said rotationpreventing means consists of spurs 18, projecting from the head or flange 17 in the same direction as the socket 16. In applying this anchoring member, its socket portion 16 is passed through a hole in the shoe bottom or tap from the upper to the inner side thereof. The spurs are driven into the sole or tap as far as permitted by the head. The sockets 16 may be made of suitable length for a single thickness of sole leather, such as the outer sole or tap, on which the socket 16 is no longer at most than the thickness of the sole, or it may be made of greater length adapted to two or more soles or thicknesses of sole leather. Thus Figure 5 shows a section of shoe bottom consisting of an inner sole 19, outsole or middle sole, 20, and tap or outsole 21. The anchoring member here shown is like that previously described, the socket 16a being long enough to extend through two of the sole members and a part of the third, and similarly an anchoring member may be placed between the insole and outsole with a socket extendin through the latter and part way through the tap 21.

Additional means 'for holding the anchoring member against rotation is shown in Figure 7, consistin of a metal plate 22, to which anchoring mem ers like those above described are secured by means of rivets 23 passing through their head portions and through the cleat, securing them together. The head portions of such anchoring members are preferably provided with spurs to be embedded in the shoe sole substance, although such spurs may beomitted and reliance placed on the connecting rivets to prevent rotation. When such plate is used, it is preferably placed between two layers of the shoe bottom, as between the insole and outsole as shown by Figure 6, rather than on the inner surface of the insole.

In construction, the anchoring member mantra head and socket are preferably integral with each other, and the s urs are made by cutting in from the rim 0 the head and bending down the sharp pointed tabs so formed.

Modifications of these details may be made without departing from the invention.

Cleats so made may be readily applied to shoes equipped with anchoring members of the character described, and as. readily removed. Thus cleats of different types may be applied alternately to the same shoe, and the shoe thus adapted for use of the ty es of athletic shoes, whether for football, gol ,running, or what not. The cleats may be provided with any suitable sort of projection or recess for engagement with a wrench, to facilitate securing them tightly and firmly to the shoe.

When applied and screwed u tightly, the raised ridge 14 on the base in ents the surface of the shoe bottom somewhat and provides a frictional attachment secured to prevent accidental disconnection of the cleat. In other words the operation of screwing the shank into the bushing orsocket, causes the ridge 14 to indent and compress a limited portion of the tread shoe bottom, so that said portion by its effort to expand, prevents accidental unscrewing rotation of the calk. Moreover said operation causes the cleat base to form a compressed base seat on the shoe bottom, preventing the calk from tipping or rocking in any direction.

It will be seen that the cleat base 12 and the anchoring member head 17, have substantially equal areas, so that when the shank is screwed into the socket, the base and head compress an intermediate shoe bottom portion of such small area that the force applied in screwing the cleat to place can readily cause the desired compression.

An advantage of the annular ridge 14 is found in the fact that the force required to compress an annular portion of the shoe bottom is less than would be required if the ridge were omitted. However, ll do not limit myself to the employment of the ridge in all cases.

I claim:

1. A cleat comprising a molded ground engaging member, having incorporated therein, a rigid reinforcing member, having an upper threaded projecting end adapted to be received in a threaded socket provided in a shoe sole, a downwardly projecting portion for reinforcing the molded ground engaging member, and for anchoring the reinforcing member thereto, and a flat disc like portion forming the sole engaging portion of the completed cleat, said disc like portion being provided with a narrow upstanding rim portion for indenting the sole.

2. An integral metallic cleat structure including a base plate, a ground engaging body depending therefrom, a threaded shank pro to be received in a, threaded socket ro'vlded in a shoe sole, and a narrow upstan ing rim portion on the base plate for indenting the shoe sole.

In testimony whereof I have afli'xed my signature.
